Intermountain Natural History Association (formerly Dinosaur Nature Association) is a private, non-profit 501(c)(3)organization created to aid the educational and scientific activities of the National Park Service at Dinosaur and Fossil Butte national monuments, the U.S. Forest Service at the Ashley, Wasatch-Cache, and Uinta national forests, and the Bureau of Land Management at the John Jarvie Ranch Historic Site. The profits from all bookstore sales are donated back to these public lands. Since INHA's inception in 1956, donations have exceeded $2.1 million. Visitor in Dinosaur Natinal Monument

Donations are given to the agencies to support specific activities or projects. These can include production and printing of newspapers, construction of information kiosks, or the financing of roadside displays, trailguides, and handouts. INHA donations help to purchase items as large as the cast skeleton of Allosaurus at Dinosaur, and as small as a roll of film for documenting projects.

INHA offers a variety of books and pamphlets about the public lands, paleontology, archeology, plants and wildlife, geology, river running, and more that are managed by the federal agencies. All items offered for sale are carefully reviewed by subject matter experts, and must be found to be educational in nature. This means that the item will not only help the visitor better understand the subject, but through this appreciation will then be supportive of efforts to properly manage and preserve them.

Our organization was founded in 1956 as the Dinosaur Nature Association. In 1999, we expanded beyond our relationship with the National Park Service to begin serving the USDA Forest Service at the Ashley, Wasatch-Cache, and Uinta national forests, and the Bureau of Land Management at the John Jarvie Ranch Historic Site. To better reflect these relationships, in 2002 we officially became the Intermountain Natural History Association.
